Relationship between the distribution of euphausiids and baleen
whales in the Antarctic (35[degrees]E-145[degrees]W).
Bone conduction is likely the predominant mechanism for hearing in fin whales and other baleen
We will also document genes involved in determining the unique characteristics of these mammals, such as loss of hind limbs, development of baleen
, and duplicated genes involved in producing myoglobin (required for storing oxygen during deep dives).
They would then tow it back to the ship, which could take hours or even days, and gradually they would remove the baleen
and strip off the blubber.
whales sometimes seek out and follow large, kilometers-wide ocean eddies and feed within them or along their edges, taking advantage of biological hot spots that are created as eddies bring cold, nutrient-rich waters to the surface.
This year's winners include: Rexford's Gifts by Annie Rexford, an arts and crafts business that takes raw material such as baleen
and ivory and produces tourism quality pieces in Barrow, Alaska; Stormi's Satellite Sales and Service by Godfrey Paul Tuckfield, a satellite installation, repair and retail operation in Point Hope; and SylviaN-Micah's Movies by Emma and Herb Kinneeveauk, a small movie rental store with small food offerings and DVD conversion services.
A variety of whale exhibits are housed there, including gray whales' bones and baleen
, huge jawbones from a blue whale, a bowhead baleen
and sperm whale teeth.
In addition to using DNA samples collected from whales over the past 20 years, the team collected genetic samples from ancient specimens -- extracted from old vessels, toys, and housing material made from baleen
-- preserved in pre-European settlements in the Canadian Arctic.
It is thought they would prey on Baleen
whales, themselves 110ft in length.

Other parts of the animal also were valuable, for instance whale baleen
(flexible plates that hang from the outer palate of these whales and used in feeding) were used for stiffening corsets and umbrellas.
Katherine Gavrilchuk, Universite Laval, is using stable isotope analysis to investigate diet in four species of baleen
whales in the estuary and gulf of the St.
